Fedora Networking :: Mapping Windows Users On Unix Users
Sep 29, 2010
Samba up and running on my pc. pc runs FC12 with kde. A laptop has win vista. The pc can access the shares on the laptop but the laptop has authentication issues to access the pc. Note that windows doesnt enforce authentication forincoming network connections.Using the system-config-samba util i tried to map a windows user to the unix user "feduser". The laptop (named LAPPY) has a user (lapuser) which has on windows no password.What should I tell samba config what the windows username should be? lapuser or LAPPYlapuser doesnt work because when accessing the pc via the laptop, the authentication fails. The only auth that is successful is when choosing the same winusername as the unix username.
Secondary, id like to setup the laptop so that the user doesnt have to provide a name and password, or at least not more then once in the lifetime of the laptop. Note that you cant provide an empty password to system-config-samba. How is that possible?
Strange but not really on issue imho:the samba - KDE control module(kcmshall4) (and the smb.conf) shows 2 shares: the homedirs and the data dir the samba server configurator (system-config-samba) shows only the datadir.

Is it possible to map a remote user to a local user in SSH? The object is to avoid using $ssh user@server and instead just do $ssh server instead.

I work as an system administrator for AIX and Linux servers. We have an FTP server running in Linux which has shared folders to Windows domain using Samba. The new requirement is to map users created to Linux machine to Windows users in such a way that, when a user logins into Windows machine with an ID say "X123" in domain "TEST", his access control to the samba shares should reflect based on the same user ID created in Linux machine.(FYI. Both the Windows and LINUX machines are in same network and domain). Please let me know the step by step procedure to configure Linux machine (smb.conf entries or any new file to be created for user mapping) to identify Windows user Login and provide access restrictions accordingly.

If I want to add Windows & Mac users as Samba users, must I first add them all as Ubuntu users? If so, since none of the other users will actually be working on the Ubuntu Server, how do I disable the other non-admin users on the Ubuntu Server login screen. I am using Webmin to administer some server settings, and command line for others.

Problem: I need to map directories to a user's home directory when they log in.
For example, I need to map /school/homework/ to user "steve" in his home directory when he logs in. I'm guessing I could use a logon script, but I can't figure out what command I should be putting in the script. I've been searching for hours through man pages and googled it a ton and can't find anything on it.

Anyway i have a very old Mandrake server where a previous owner hosted mailboxes on. This server is getting very slow and does alot of e-mail related tasks like:popsmtpmxIt runs on sendmail (which is also very outdated...) and it doesnt seem to respond to its config files. And the whole smtp and mx thing leaves us with some really weird mail problems...So i want to implement it in our current mail setup in which i have it all on seperate servers:2 smtp server (dns roundrobbing) (postfix)4 mx servers (1 etrn) (postfix)1 webmail server (v-webmail) (just apache and connects to the pop/imap server)And 1 pop/imap server (postfix, dovecot)I also want to implement smtp authentication because of all the mobile clients i have to host... This is where it gets tricky.
I want to export the unix user table of the old mandrake server and import that into a mysql database. This database will be used to authenticate the smtp users.I also want the export of the unix users to import it to the other pop/imap server so users can logon to that server instead of the crappy Mandrake server.I would expect that the export from unux users to mysql (including passwords) is the hardest part. I googled it, but some of the stuff i found didnt seem to be very reliable, so thats where you guys kick in :-). So is this possible? If so, how can i do it?I know i should go with some kind of ldap situation but that seems a way bigger hassle then this setup.

I've set up an email server as per this howto: [url]
In a nutshell, it uses a combinatio of postfix, dovecot, amavis (ClamAV and SpamAssisan) and mysql.
However, with this setup, authenticated users are able to spoof outgoing message by simple changing the "from" tag.
Does anyone have any ideas on how I could implement some address mapping to users?
In this setup, postfix users are NOT system users, by are stored in the database.

I have setup a Centos5.5 VMWare guest with Samba and Winbind for Active Directory integration, using GUI tools. Authentication works flawlessly, with automatic home directory creation. What I want to achieve now is using local UNIX groups to controll access to shared folders, to avoid bothering AD administrators with groups management. This is my smb.conf global section:
workgroup = COGITANS
password server = domainserver.hq.cogitans.it
realm = HQ.COGITANS.IT
security = ads
[code]....
'finance' is a local UNIX group where I added user 'COGITANSalberto' (I also tried with 'alberto') as a secondary group (primary group is 'domain users' and it cannot be changed). I am sure the user is added, because it is listed in 'getent group'. If I specify user COGITANSalberto in valid users it works, i.e. only that use can access the share, the others get a NT_STATUS_ACCESS_DENIED error. But if I use +finance, access is denied to everybody, and this is the log:
[2010/09/11 14:12:37, 10] smbd/share_access.c:user_ok_token(211)
User COGITANSalberto not in 'valid users'
[2010/09/11 14:12:37, 2] smbd/service.c:make_connection_snum(617)
user 'COGITANSalberto' (from session setup) not permitted to access this share (finance)
[code]....
It seems like winbind cannot recognize finance as a local group. For the same reason, I guess, 'force group = finance' does not work either (files are created with 'domain users' group ownership). My /etc/nsswitch.conf:
passwd: files winbind
shadow: files winbind
group: files winbind
Grants and ownership on the '/repositories/shared/finance' folder are
root:domain users with permissions 775

We have an existing Windows 2000 network that I am trying to add an Ubuntu 8.04 server to. I have put links into the windows domain DFS to the linux machine's samba shares.
The shares work fine for local users that are physically on the same network (192.168.0.X). Remote users from other offices or dialing in with a vpn client can not access the these particular folders off the DFS. However, they can map them directly from the ubuntu server.

I have an ubuntu 11,04 samba domain server, I want to also configure this machine to work as a dhcp server, however this have give me some issues with te windows 7 workstations, my guest is that it have something to do with the iptables because those station do join the samba domain went both server and workstation are conected to a router.
This is the script I use at boot
Code:
#FOR SHARED INTERNET
/sbin/iptables -P FORWARD ACCEPT
/sbin/iptables --table nat -A POSTROUTING -o eth2 -j MASQUERADE
[code]....
I haven't test it with windows xp station but I have use the same code in the past with no problems, and since this is my first time joining windows 7 station i belive there must be some other port that need fowarding.

I am currently trying to set up a Samba domain server. In the Samba-HOWTO-Collection I found an
example file.(Point 3.3.3.1) In the explanations of the example below, the author says I need to map UNIX Groups to NT Groups. He writes a shell-script of how one could do it, but when I copy it and then execute it, I get the error:
Bad option: rid=512
Bad option: rid=513
Bad option: rid=514
The other groups do get mapped, just the Domain Admins, Domain Users and Domain Guests dont. This is the shell from the HOWTO:
#!/bin/bash
#### Shell-Skript f ̈r sp ̈tere Verwendung aufbewahren
net groupmap modify ntgroup="Domain Admins" unixgroup=ntadmins rid=512
net groupmap modify ntgroup="Domain Users" unixgroup=users rid=513
net groupmap modify ntgroup="Domain Guests" unixgroup=nobody rid=514

We are trying to set up a classroom training environment where our SIG can hold classes for prospective converts from Microsoft/Mac. The ten machines will have /home/student01..10 and /home/linsig01..10 as users. We want /home/student01 to be able to explore and sudo so they can learn to administer their personal machines at home. We don't want them to be able to modify (sudo) /home/linsig01. I've seen the tutorial on Access Control Lists but I'd like other input so we get it right the first time.

In other Linux distros I've used, new users are assigned to their own group (i.e. user 'joe', group 'joe') by default. To my surprise, when I create new users with my openSUSE 11.4, they are all assigned to the 'users' shared group by default.To test this, I created a new user called 'friends'. From my terminal, I can see how the new user files look like:
joe@linux:~> ls -l /home/friends/
total 40
drwxr-xr-x 2 friends users 4096 Sep 3 11:37 bin

I have inherited a RedHat 5.4 server that is having an odd issue. Root and all of the user accounts can log in via SSH. Not a single account can log in via the console (sitting in front of the server). If I bring it up in single user made, I can log in with root all day long.
I want to say that this has something to do with PAM, but this is when I play my "Noob" card. Could anyone possibly steer me in the right direction to figure out what is going on?

I have FC-4 with Squid and Dansguardian. Internet Users in my organisation are configured to use proxy with 8080 in browser IE. There's no issue with Users as DG working perfect for them. We have Business Development Team, as they need to do most of the research over internet, their IP's are included into "Exception IP List" in Dansguardian. Obviously these people will be excepted from all banned sites, BD Team able to do chat, play games and do social networking and other stuff over the net, which results in more bandwidth consumption and breaking office policies.
I have tried to implement SQUID ACL's to block few sites like " meebo.com, orkut.com,facebook.com etc" but SQUID acl's not coming into picture. any one who successfully blocked chat, banned sites and social networking in DG with my case.
